Which question can be tested through an experiment?

Answer and explanation

Correct answer: Does sugar dissolve faster in hot water than in cold water?

Option C can be tested experimentally because the water temperature can be changed and the time taken by sugar to dissolve can be measured. Choices such as whether blue is beautiful or music is good depend on personal opinion, so they do not have one definite experimental answer. Exam tip: A question involving measurable variables and comparison is usually testable.
